runt BURNER.

Application filed December 21, 1923.

To all whom t may concern.'

Be 1t known that we, MURRAY E. Piron and lTHoMAs S. PAGE, citizens ofthe United lwherein liquid fuel being delivered to a burner nozzle isadapted to pass through a retort casing overlying the burner nozzle toeffect preheating and vaporization thereof before passing to the burnernozzle.

Another object of the invention is to provide a fuel burner of theretort type wherein a retort casing overlying a burner nozzle carries aprotuberance or projection of increased cross-sectionalarea upon thelower side thereof adjacent the burner nozzle to absorb the `maximumquantity of heat from the nozzle for preheating and vaporizing theliquid fuel in the retort chamber prior to its delivery to the burnernozzle.

The invention further provides a settling chamber in the retort of theburner for the collection of a quantity of the liquid fuel in itspassage through the fuel supply pipe to the burner nozzle wherebygreater quantity thereof may be preheated and vaporized priorfto itsdischarge and ignition at the discharge burner nozzle.

With the above and other objects in view that will become apparent asthe nature of the invention is better understood, the saine consists ofthe novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designatecorresponding parts throughout the several views,

Figure 1 is a vertic-al side elevational view, partly shown in sectionof a fuel burner constructed in accordance with the present invention,showing the enlarged retort chamber overlying the burner nozzle with thedrip pan disposed below the nozzle and retort,

Figure 2 is a horizontal sectional view taken on line H-1I of Fig. 1,and

Figure 3 is a bottom plan view of the retort.

In the accompanying drawing which Serial No. 622,071.

shows the preferred embodiment of the present invention, the referencenumeral 5 designates'a fuel pipe having a threaded lower end G adaptedfor connection with an ordi nary type of fuel supply pipe that is valvecontrolled in any preferred manner, the fuel pipe 5 being externallythreaded from its lower end upwardly, as at T, intermediate the upperand lower ends thereof and freely passing through an opening 8 providedin the plate 9 that extends laterally therefrom and is preferably of theconfiguration in plan view as illustrated in Fig. 2. 'lhe plate 9 isretained in position upon the fuel pipe by the nuts 10, respectivelypositioned above and below the plate and engaging the threads 'i' on thesupply pipe for rigidly supporting the plate 9 in position thereon.

A retort in the form of a hollow casing is associated with the upperend, of the fuel pipe 5 and embodies upper and lower walls 11 and 12respectively, and end walls 13 4and 14. An elbow 15 is mounted on thethreaded upper end 16 of the fuel pipe 5 and carries a reduced threadedstem 17' at its other end that is threaded into the internally threadedoutwardly extending boss 18 carried by the end wall 13 of the retortcasing. Thebottom y wall 12 pf the retort casing carries a depend ingprojection or protuberance 19 at the cen.

tral portion thereof providing an area of increased cross-section asillust-rated in. Fig. 1 for purposes presently to appear.

A. vertical pipe section 2O is associated with the end wall 14 of theretort casing, the same being disposed above the plate 9 with an elbow21 threaded upon t'n Wupper end thereof and carrying a reduced threadedl stem 22 that is threaded into the outwardly directed tubular boss 23carried by the end wall 14 of the retort casing. An elbow 24 is threadedon the lower end of the pipe section 20 with the lower side of saidelbow resting in the cavity 25 formed in the upper side of the plate 9adjacent the outer end thereof to constitute a support for the pipesection 2O and the adjacent end of the retort casing. The upper .face ofthe plate 9 is provided with a relatively large cavity 26 con stitutinga drin pan and over which the short pipe section 27 threaded into theadjacent end of the elbow 24 is disposed.

The burner head includes an elbow 28 having the pipe section 27 threadedinto one end thereof with the elbow 28 perpendicularly positioned asillustrated, the upper end thereof being,` slightly reduced andexternally threaded for the reception of a sorew Tap 29 having a centralburner jet opening 30.

The burner head is disposed directly beneath the protnberance orxrojection l) depending from the lower wall l2 of the retort easing andthe ilaine issuing frein the burne jet opening 3G is directed againstsaid protnberanee to conveyv the 'reatest possible amount, of heatther'`l "r `piid fuel passing through the fuel pipe enters lh" retorteasing and settles in the lo r i thereof to the lori'lsontal level ofthe ellirorf attaching; Steins Il? :11nd thereafter flowing 'through theelbow 2l, pipe il), elbow and pipe seeton 22' to the borner heed dripsinta;

lllhat is claimed as new is ln a burner of the class described, avertieallgY dis Josed fuel supply pipe hziving its lower portion screwthreaded, an elbow earried by the upper end of said pipe, a retortconnected to the elbow, a drip pan neunted on the threaded portion ofthe fuel supply pipe to inove vertically thereon, adjusting' nuts onsaid threaded portion of the fuel supply pipe above and below the drippan to adjust the position of the latter on the fuel supply pipe, eburner heed 'snpported by the drip pan, and al pipe connertion betweenthe burner head and retort.

2. ln a burner of the class described, a vertically disposed fuelsupplyv pipe having its lower portion screw threaded, an el.- bowcarried by the upper end of said pipe, a retort connected to the elbow adrip pan mounted on the threaded portion'of the fuel suppl)v pipe toinove vertically thereon, adjusting nuts on said threaded portion of thefuel suppl;v pipe above and below the drip pan to' adjust the positionof the latter on the fnel suppl;vv pipe, a burner head supported by thedrip pan, and i pipe Connection between the burner head and retort, saiddrip pan having a drip recess wherein the lower part of said pipeconnection rests and being` laterallyY :itended on each side thereof toprovide heat conserving` means.
